I'm looking at getting me a new DSLR, and the Canon Rebel XT is at the top of my list. How is this camera? It seems quite good from what I've read, but more info never hurts. I found a deal at amazon.com, it includes the XT and Canon's EF-S 18-55mm, f3.5-5.6 zoom lens. Is this lens a good all-around one? I mostly shoot landscape stuff, trees, treelines, sunsets, etc. I figure I'll add a battery grip at least. What else should I get for it? I imagine a case and maybe a flash? Any info would be greatly appreciated. Thanks!
